Abstract
A communication device, method and computer program product reduce time to connect a communication session. The communication device registers for cellular communication service using a first radio access technology (RAT) or sub-RAT with a first node. The communication device determines whether a connection for a selected communication service is predicted to be available from the first node. The communication device determines whether a request for the selected communication service is predicted to occur. In response to determining that the connection for the selected communication service is unavailable from the first node and the request for the selected communication service is predicted to occur, the communication device identifies a second node that supports communication using a second RAT/sub-RAT. The communication devices triggers registration fallback from the first node to the second node. In response to receiving the request, the communication device connects to the second node for the selected communication service.
